Currently, one of the priority guidelines of the World Health Organization is to strengthen the information, evidence and research systems for mental health. The problem of mental health has a significant magnitude in relation to the Sustainable Development Goals (SDGs), recommended by the United Nations (UN), which indicate in its third goal, good health and well-being and, as a specific objective to reduce by one third premature mortality from noncommunicable diseases through prevention and treatment, and promote mental health and well-being, as an agenda for 2030. The Global Burden of Disease, Injury and Risk Factors (GBD) study revealed the high rates of disability and mortality among people with mental disorders, exposing the hidden burden of people with mental health problems worldwide. According to data from the World Health Organization, it is estimated that in Brazil, for every 100 people, 30 may develop mental health problems. Among these, depression (5.8%) and anxiety (9.3%) are the main health problems. This scenario is changing because of the unexpected pandemic of COVID-19, which started in 2020, accounting for 45% of all new cases of this disease worldwide and 48% of all new deaths attributable to the disease. The pandemic is having a profound impact on the mental health and well-being of many people around the world, contributing to the burden of new mental health problems and the worsening of pre-existing illnesses, adding to the fact that many countries significantly interrupted care in mental health services during the pandemic. In view of the above, it is necessary the development of researches that can use the population surveys as subsidies to the formulation and evaluation of public policies, becoming increasing in several countries as a tool to support health planning. Thus, this proposal aims to search for studies on population health surveys, which address collection strategies and data analysis on epidemiology of mental disorders, in order to support future investigations.
